Thank you for your interest in Pratt + Larson! Unfortunately, the tile in the foreground and on the walls, ceiling and floor of this amazing bathroom is not our handmade ceramic tile. It looks as if it may be a type of honed limestone. Our showroom partner in Austin Texas, Architectural Tile & Stone sold this job for us. You might reach out to them and see if they have some insight as to what material was used. https://architecturaltilestone.com Hope this helps! Thanks again for your interest.
